Vacuum transmission parts wear is a common problem, including bearing position, bearing, bearing chamber, keyways, thread etc.parts. The traditional method is welding and brushing electroplating, but there are some drawbacks for both methods: welding high temperature can not be completely eliminated and willbe causing material damage easily, bent or broken parts; Brushing electroplating have a strict limit on the thickness and easily to be dropped. Besides, both of this two methods are using metal repair but cannot change the clearance, it willbe got wore again through other force.
Vacuum pump can be divided into a comprehensive form of corrosion (uniform) corrosion and localized corrosion two categories, the former occurs in more uniform vacuum all surfaces, the latter only occurs in localized, such as pitting, crevice corrosion, intergranular corrosion, stress corrosion . Safety performance polymer composites using a vacuum pump to surface organic coating on the corrosion, it has good chemical resistance and excellent mechanical properties and adhesion properties, repair compared with traditional pressure vessel welding, with simple construction, low cost, repair good effect.
Vacuum due to casting, machining defects, stress and other factors often result in overloaded parts cracks or breakage. Conventional repair method is the use of welding, but some parts to be cast iron, aluminum, titanium, it is difficult to do soldering process. There are some easy-to-explosion of dangerous situations, more difficult welding repair method. Mei Wah technology is a "cold welding" technique to avoid heat stress and deformation, while the overall performance material good adhesion and compressive strength, corrosion resistance, etc., can satisfy the requirements of various equipment components, resulting in the lowest lower input costs effectively guarantee production. Safe, convenient, and reliable.
